One vote for the Topeak Road Morph pump. I have several Zefal HPXs, and the Road Morph is much easier to use and get the tire up to sufficient pressure. It comes with a frame-mount bracket but I pack mine in my seat bag. OK, it's a big bag. I've tried those quick patches and my take is they're only good enough to get you a few miles. One 30-mile death march required a hole to be temp-patched 3 times. In fairness, they seem to work better than that for people who have low-pressure tires and fat tubes that don't have to expand to fill the inside of the tire.
I like to carry a quik-link because it's small and I have lots of extras from previous chains. The outer link is always the one to fail, so a QL will *always* fix a chain. I actually had a link fail last week. The chain was relatively new and well-lubed, it just literally came apart two miles into a ride.
Finally, I carry a multi-tool. I only need the basics: a 3,5, and 6mm allen wrench and maybe a phillips. Tire irons are only good for pinching a new tube; if you must use one, use a
Quik Stik; it'll zip the tire off without damaging the tube.
